ZEBULON HUNT, OF HUDSON, NEW YORK.

IMPROVEMENT I N BASE-BURNING STOVES.

Specification forming part of Letters Patent No. 86,017, dated January 19, 1869.

Be it known that I, ZEBULON HUNT, of the city of Hudson, in the county of Columbia and State of New York, have invented a new and useful Improvement in the Construction of Stoves and F urnaces; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which Figure 1 is a perspective view of a stove with reservoir and improvement. Fig. 2 is a transverse section from front to rear. Fig. 3 is a transverse section from right to left. Fig. 4 is a horizontal section of bottom from right to left. Fig. 5 is a horizontal section of bottom from front to rear.

Red darts on the drawings indicate the direction and course of the hot-air drafts or currents, and the black darts the direction and course of the cold-air or draft proper.

The nature of my invention consists in providing coal-burning stoves in which reservoirs or magazines for reserve coal are used, and furnaces for heating dwellings, &c., with a circular hot-air flue entirely encircling the bottom of the same next to or adjoining the exterior casing or shell.

To enable those skilled in the art to make and use my invention, I will proceed to de scribe its construction and operation.

I construct in the bottom of a coal-burning stove or furnace a flue, F, entirely surrounding the base within, and adjoining the extcrior shell or casing, to receive the hot air from the flue D and conduct it around and into the line D. These fines D D are separated throughout by a partition. (See Figs. 1 and 2.)

The flue F has an inclined or sloping top, in common with and in the same plane of inclination as the top of flue G. This common top or covering of the two flnes forms a funnel-shaped bottom to the hot-air chamber H surrounding the fire-pot P, and thus usefully employs a portion of the space or chamber around the fire-pot, which is generally unoccupied; and in doing this I lose none of the advantages of heating the base of the stove, but by so economizing the space increase the heating-surface, and consequently the radiation of the bottom of the stove, while I at the same time preserve the draft unimpaired.

I to construct and locate the reservoir in my stove as to allow all the hot air in the combustion-chamber I I arising from the top of the fire-pot to entirely envelop and surround it, (excepting only the space occupied by the door 0) and at the same time to come in direct contact with the shell or outer casing of the stove, both top and sides, the reservoir being fed or supplied with coal through the door 0 in the front of the stove instead of through the top, as is more usual in other reservoir-stoves.

From this description, aided by a reference to the annexed drawings, it will be readily seen that all the heat produced from the fuel employed is brought into direct contact with the whole outer shell or casin g of the stove, so that the greatest possible amount of heat and radiation is obtained.

I employ the flues F and G in the construction of furnaces for heating dwellings, &c., as well as in stoves, and claim for them (these fines) the same advantages in the one as in the other when employed in combination or connection with the lines D D.

What I claim, therefore, as my invention, and desire to secure by Letters Patent of the United States, is-

1. The circular fines F and G in all coalburning stoves and furnaces in which a fuelmagazine or supply-chamber is employed, when such lines are combined, located, and constructed as or substantially as and for the purposes set forth.

2. The combustion-chamber I I in stoves having a reservoir for reserve coal, and in furnaces when such chamber is connected with the circular flue F by means of the descending flue D, substantially as and for the purpose set forth.

3. The combination and arrangement of chamber I I, descending flue D, circular flue F, and ascending flue D in stoves in which the supply-reservoir is employed, and in furnaces, when the chamber I I is entirely separate and shut oif from the hot-air chamber H surrounding the fire-pot P, substantially in the manner and for the purpose herein set forth.
